Can I make a checkbox populate the current date?

Question

I've been asked to make a form that has quite a few checkboxes.  These checkboxes also need to be marked with a date when checked off.
Rather than have the person filling out the form type the date every time they check the box, they request that when the user clicks the checkbox that a current date show next to the checkbox.
I don't know if this can be done with a current date stamp or with having a text box that populates with the current date, etc.
The forms are also going to be used throughout multiple days, so I can't just call on a "current date" and show/hide that text box like I had originally thought to do.
I'm also really green to scripting so any help or guidance in the right direction would be much appreciated.
Thank you.

Answer 1

The following Mouse Up script for a check box will set the associated text field to the current data when it's selected, and blank the field when not:
// Mouse Up script for check box
(function () {
    // Get a reference to the text field
    var f = getField("text1");
    // Set the value of the text field
    if (event.target.value !== "Off") {
        f.value = util.printd("mm/dd/yyyy", new Date());
    } else {
        f.value = "";
Replace "text1" with the name of the associated text field.
